 Flutter is Google's SDK for crafting beautiful, fast user experiences for
 mobile, web, and desktop from a single codebase. Flutter works with existing
 code, is used by developers and organizations around the world, and is free and
 open source.

 ## Documentation

 * [Install Flutter](https://flutter.dev/get-started/)
 * [Flutter documentation](https://docs.flutter.dev/)
 * [Development wiki](https://github.com/flutter/flutter/wiki)
 * [Contributing to Flutter](https://github.com/flutter/flutter/blob/master/CONTRIBUTING.md)

 For announcements about new releases, follow the
 [flutter-announce@googlegroups.com](https://groups.google.com/forum/#!forum/flutter-announce)
 mailing list. Our documentation also tracks [breaking
 changes](https://docs.flutter.dev/release/breaking-changes) across releases.

 ## Terms of service

 The Flutter tool may occasionally download resources from Google servers. By
 downloading or using the Flutter SDK, you agree to the Google Terms of Service:
 https://policies.google.com/terms

 For example, when installed from GitHub (as opposed to from a prepackaged
 archive), the Flutter tool will download the Dart SDK from Google servers
 immediately when first run, as it is used to execute the `flutter` tool itself.
 This will also occur when Flutter is upgraded (e.g. by running the `flutter
 upgrade` command).

 ## About Flutter

 We think Flutter will help you create beautiful, fast apps, with a productive,
 extensible and open development model, whether you're targeting iOS or Android,
 web, Windows, macOS, Linux or embedding it as the UI toolkit for a platform of
 your choice.

 ### Beautiful user experiences

 We want to enable designers to deliver their full creative vision without being
 forced to water it down due to limitations of the underlying framework.
 Flutter's [layered architecture] gives you control over every pixel on the
 screen and its powerful compositing capabilities let you overlay and animate
 graphics, video, text, and controls without limitation. Flutter includes a full
 [set of widgets][widget catalog] that deliver pixel-perfect experiences whether
 you're building for iOS ([Cupertino]) or other platforms ([Material]), along with
 support for customizing or creating entirely new visual components.

 ### Fast results

 Flutter is fast. It's powered by the same hardware-accelerated 2D graphics
 library that underpins Chrome and Android: [Skia]. We architected Flutter to
 support glitch-free, jank-free graphics at the native speed of your device.
 Flutter code is powered by the world-class [Dart platform], which enables
 compilation to 32-bit and 64-bit ARM machine code for iOS and Android, as well
 as JavaScript for the web and Intel x64 for desktop devices.

 ### Productive development

 Flutter offers [stateful hot reload][Hot reload], allowing you to make changes to your code
 and see the results instantly without restarting your app or losing its state.

 ### Extensible and open model

 Flutter works with any development tool (or none at all), and also includes
 editor plug-ins for both [Visual Studio Code] and [IntelliJ / Android Studio].
 Flutter provides [tens of thousands of packages][Flutter packages] to speed your
 development, regardless of your target platform. And accessing other native code
 is easy, with support for both FFI ([on Android][Android FFI], [on iOS][iOS FFI],
 [on macOS][macOS FFI], and [on Windows][Windows FFI]) as well as
 [platform-specific APIs][platform channels].

 Flutter is a fully open-source project, and we welcome contributions.
 Information on how to get started can be found in our
 [contributor guide](CONTRIBUTING.md).
